<h3>Answer:  36%</h3>

============================================

Explanation:

There are 20 blue cards out of 10+20+25 = 55 cards total.

Divide the 20 over 55 to get

20/55 = 0.363636...

where the "36"s go on forever

So 20/55 = 0.3636 approximately

Move the decimal point over 2 spots to go from 0.3637 to 36.37%

Then round to the nearest percent: 36.37% ---> 36%

The probability of getting a blue card is approximately 36%
